Secondly, as shown in Figure 6, relative level face is configured in the mode tilted downwards from disc type framework 20 side towards framework connecting member 12 side first passenger's holding components 41.
In addition, second passenger's holding components 42 is configured in horizontal surface or is configured in the mode tilted upward towards framework connecting member 12 side from disc type framework 20 side.
Therefore, because passenger's holding components 40 is easier to the shape of following passenger's buttocks, the passenger taken one's seat can obtain good fit sense.
In addition, the angle of inclination of first passenger's holding components 41, the passenger's buttocks shape depending on general physique with the angle of inclination of second passenger's holding components 42 sets, and the angle of inclination in first passenger's holding components 41 to the second passenger holding components 42 relative level face is larger.
Secondly, the front ends of first passenger's holding components 41 as shown in Figure 6, is configured at disc type framework 20 rear end more top.
Namely, being configured to, considering the load for applying during seating passengers, cushion rubber 3a and first passenger's holding components 41, in the amount of bow of above-below direction, during seating passengers, are general plane from disc type framework 12 to the first passenger holding components 41.
Therefore, high tracing ability can be possessed for seated occupant, improve sense of taking one's seat further.
In addition, because first passenger's holding components 41 is to be configured at the mode hypsokinesis of the rear end more top of disc type framework 20 by front ends, the rear end of disc type framework 20 is easily to the formation that first passenger's holding components 41 side extends.Thus disc type framework 20 and first passenger's holding components 41, for being easy to the formation of configuration continuously, can further improve sense of taking one's seat.
Secondly, first passenger's holding components 41 and second passenger's holding components 42 as shown in Figure 6, are configured at the more top above framework connecting member 12.
In addition, the front ends of first passenger's holding components 41, and the rear end of second passenger's holding components 42 is configured at the plane more top formed by disc type framework rear end and framework connecting member separately above.
Therefore, passenger's holding components 40 is configured at the position close to passenger's buttocks of taking one's seat on above-below direction, and the tracing ability for passenger via cushion rubber 3a can further improve.In addition, due to the lower thickness of cushion rubber 3a, seat lightweight, miniaturization can be made.
The mode that passenger's holding components 40 of the present embodiment forms general plane with the face relatively abutting cushion rubber 3a extends in the lateral direction, but can appropriately change.
As other embodiments, also can possess the middle body of the left and right directions of passenger's holding components 40, the face that relatively abuts cushion rubber 3a is vertical, to cushion rubber 3a against the kink of lateral buckling.
Middle body due to this passenger's holding components 40 is positioned at the position of the recess 30 of corresponding disc type framework 20, during seating passengers, by the kink of recess 30 and passenger's holding components 40, can relax the impact applied passenger's crotch part further.Thus, can further improve the sense of taking one's seat of passenger.
In addition, in the above-described embodiments, be illustrated as the front stall of concrete example to automobile, but be not limited thereto, be undoubtedly also applicable to middle seat, the back seat of automobile.
